If user selects the picture in print screen 500, then show the print screen 510 shown in Fig. 5 B.As an example, shown here print screen 510 is in the state that have selected picture 501.Reference numeral 511 represents the picture of user selected in print screen 500.Show selected picture in an exaggerated way, thus make user be easier to confirm selected by picture.When user wants to change setting of printing, user selects icon 512.When user wants picture (print screen 500) being back to the list Showed Picture, user selects icon 513.
Under the state of display print screen 510, if portable terminal 100 is placed in the position of the NFC label near printing device 110 by user, then short-range communication unit 210 reads the information be stored in the NFC label of printing device 110.In the present embodiment, be stored in the information in the NFC label of printing device 110, comprise wireless communication unit 211 and printing device 110 and carry out the link information (the IP address of the SSID of access point 120, the safe key used when being connected to access point 120 and printing device 110) that radio communication uses.Based on the link information that the NFC label reading printing device 110 by short-range communication unit 210 obtains, wireless communication unit 211 can carry out radio communication with printing device 110.Note, replace the IP address of printing device 110, link information can comprise the MAC Address of printing device 110.
But when having carried out Wi-Fi setting thus make Wi-Fi invalid in setting screen 400, even if when short-range communication unit 210 gets link information, wireless communication unit 211 has not also carried out radio communication.User, portable terminal 100 is placed in before the position of the NFC label of (or contact) printing device 110, arrange if user manually changes Wi-Fi thus make Wi-Fi effective, so carry out the switching using NFC, and allow wireless communication unit 211 to carry out radio communication.But for this reason, user needs to carry out troublesome manual operation and changes over active state to be arranged by Wi-Fi.In addition, some users for how operating portable terminal 100 and do not have enough knowledge may be there are.Also may there is the user not knowing can use for changing the function that Wi-Fi is arranged.In the present embodiment, in order to tackle above-mentioned situation, when portable terminal 100 being placed in the position near the NFC label of printing device 110, in other words, when short-range communication unit 210 gets link information from NFC label, Wi-Fi is arranged and automatically changes over active state from inactive state.User is made manually to change over active state without the need to being arranged by Wi-Fi like this.In addition, though when user for how to operate portable terminal 100 there is few knowledge time, when user not can be appreciated that change, also Wi-Fi can be arranged and automatically change over active state.
When short-range communication unit 210 gets link information from NFC label, Wi-Fi arranges change unit 303 and Wi-Fi setting is changed over active state from inactive state.Responsively, communication unit 302 is based on obtained link information, and instruction wireless communication unit 211 is connected to access point 120.When wireless communication unit 211 is connected to access point 120, print job generation unit 305 generates print job, and generated print job is sent to the destination specified by the IP address passed through included by obtained link information, that is, printing device 110.In this stage, by picture control unit 301, the print screen 520 shown in Fig. 5 C is presented on guidance panel 206.When completing the transmission of print job, by picture control unit 301, the print screen 530 shown in Fig. 5 D is presented on guidance panel 206.
Then with reference to the flow chart shown in figure 6, the following describes the process carried out when print job is sent to printing device 110 by portable terminal 100.The control program be stored in the memory of such as ROM 202 grade to be loaded in RAM 203 by CPU 201 and to perform this control program, processing the step in the flow chart shown in Fig. 6.
Under the state that user selects user to want the picture printed (namely, under the state of display print screen 510), if portable terminal 100 is placed in the position of the NFC label near printing device 110 by user, so in step S601, short-range communication unit 210 uses short haul connection, obtains link information from NFC label.Being stored in the link information in the NFC label of printing device 110, comprising the information of the IP address of the SSID information representing access point 120, the information representing the safe key used when being connected to access point 120 and expression printing device 110.
If short-range communication unit 210 gets link information from NFC label, so in step S602, memory cell 306 initializing variable WiFi_Flag.
Then judge Wi-Fi arranges whether be set in inactive state in step S603, CPU 201.By CPU 201 with reference to the information be stored in the memory of such as HDD 204 grade, carry out this judgement.
When in step S603, CPU 201 is judged as that Wi-Fi setting is in inactive state, handling process enters step S604.Change unit 303 is set at S604, Wi-Fi Wi-Fi setting is changed over active state (arrange from OFF and change over ON setting) from inactive state.As the result of the process of step S604, state changes over the state allowing wireless communication unit 211 to carry out radio communication.In step S605, memory cell 306 substitutes into variable WiFi_Flag by 1.Note, variable WiFi_Flag is the variable for managing the change that Wi-Fi is arranged.By substituting into variable WiFi_Flag in step S605 by 1, print application 300 obtains expression and arranges by Wi-Fi the information that change unit 303 changes Wi-Fi setting automatically.
Because Wi-Fi arranges change unit 303, Wi-Fi setting is changed over active state automatically from inactive state, thus become and carry out troublesome manual operation to change Wi-Fi setting without the need to user.In addition, though when user for how to operate portable terminal 100 there is few knowledge time, when user not can be appreciated that change, also Wi-Fi can be arranged and automatically change over active state.
On the other hand, being judged as that Wi-Fi is arranged at CPU 201 in step S603 is not that when being in inactive state, handling process enters step S606.When handling process enters step S606, Wi-Fi arranges and is in active state, therefore without the need to carry out as step S604 the change that arranges of the Wi-Fi that carries out.But, the access point in connecting is switched to access point 120, and may wish after recovery with by be connected switch to access point 120 before the connection of initial Access Point that connects.Therefore, in step S606, memory cell 306 stores the information of the access point represented in current connection.Such as, at wireless communication unit 211 the current access point that is wi-fi_network_001 with SSID be connected in, in step S606, this SSID is stored in memory cell 306.Note, there is the possibility that portable terminal 100 has been connected to access point 120.In this case, the SSID included by the link information that step S601 obtains is identical with the SSID of the access point that portable terminal 100 is connected with current.Even if in this case, the switching of the also access point of generation step S607.
